This paper studies behavior in experiments with a linear voluntary contributions mechanism for public goods conducted in Japan, the Netherlands, Spain and the USA. The same experimental design was used in the four countries. Our 'contribution function' design allows us to obtain a view of...

Competition typically involves two main dimensions, a rivalry for resources and the ranking of relative performances. If socially recognized, the latter yields a ranking in terms of social status. The rivalry of resources resulting from interacting under a competitive incentive scheme has been...

We study how the number of traders affects the interaction between a centralized exchange and bilateral negotiations in an experimental labor market with excess supply and incomplete contracts. Our large markets are three times as large as our small markets. In bilateral negotiations firms...

This paper studies experimentally how firms choose between using a centralized market and bilateral negotiations to recruit new personnel. In the market firms interact with several workers but do not have information about workers' behavior in the past. In the bilateral negotiations firms...

We use experiments to study the efficiency effects for a market as a whole of adding the possibility of forward contracting to a pre-existing spot market. We deal separately with the cases where spot market competition is in quantities and where it is in supply functions. In both cases we...
